Syringa Vulgaris (Lilac) Extract is a plant-derived ingredient containing verbascoside and other polyphenols, used in skincare for its antioxidant, anti-inflammatory, and antimicrobial properties. It is sometimes promoted for helping calm blemish-prone or sensitive skin.

|---|---|---|
| Contact irritation (redness, stinging) | Uncommon | More likely with concentrated extracts or on compromised skin barriers. |
| Allergic contact dermatitis | Rare | Botanical extracts can sensitize predisposed individuals; patch testing advised. |
| Photosensitivity reactions | Very rare | Limited evidence; plant polyphenols are generally not strongly phototoxic. |
